Ah, I understand. I don't see any problem with allowing people to carry their blades as long as their not poking people with them, heheh. Although I suppose it would give a whole new definition to a street brawl if that happened to happen.
I think that might lower the frequency of street fights, due to it becoming an almost-certain life-or-death situation.
Hmmm...well, Randy Couture would be a favorite of mine: he's just remarkable. Fedor is one of my favorite fighters to watch - he's a machine. Nate Diaz has really nice ground game right now, I always enjoy his matches.
Wow. This is a tough question, heheheh.
So many great fighters!
I think it would be very wrong of us not to at least give an honorable mention to fighters like Anderson Silva, Rory Singer, Josh Hanes...
